How can i pass object from class thread to post? - c++

Question

Hello on line 88 I get an error that says no matching function for call to Post::Post(int&, std::string* [4], std::string* [4], std::string, const char [10]) and also candidate expects 1 argument, 5 provided! I am not so good with C++ so I cannot understand what I am doing wrong! I want to pass objects from class Thread to class Post! Thank you very much.

Answer 1

Reading the error, you have the following constructor:
Post(int id, std::string title, std::string creator, std::string text, std::string date)
You are trying to call it with the following arguments:
Post(int&, std::string* [4], std::string* [4], std::string, const char [10])
The int& -> int conversion is allowed, as is the const char[10] -> std::string.
That leaves the std::string*[4] -> std::string conversion. That is not allowed.
Did you perhaps mean to pass *thread->postTitles[0] or somesuch?

Answer 2

A second problem will occure as new instanciate the Post object but returns the pointer to the allocated memory. That means you have to change
Post tempPost = new Post(...)
to
Post * tempPost = new Post(...)

Answer 3

Regrading the error.
Need changes some statements as given below.
string *postTitles[4];
string *postCreatorNames[4];
Post tempPost = new Post(PostID, thread->postTitles,thread->postCreatorNames, thread->GenerateText(),"30-1-2017");
to
string postTitles[4];
string postCreatorNames[4];
Post *tempPost = new Post(PostID, thread->postTitles[ThreadNo],thread->postCreatorNames[ThreadNo], thread->GenerateText(),"30-1-2017");
Hope this will work for you.
